LUBRICATOR.

Specification of Letters Patent.

Application 1116a August 14,1906. Serial No, 330,646.-

To all whom it may concern: I

Be it known that we, CHARLES LAYr E'rTE Deer ,Lodge, in the county of Powell and State of Montana, have invented a new and Improved Lubricator, of which the'following is a full, clear, and exact description.

' This invention relates to lubricators, and is particularly useful in connection with devices of'this character employed for the purpose of lubricating steam-engine cylinders.

- The object of the invention is to rovide a I lubricator simple, strong, and durab e in coni struction and in which the oil or other lubricant may befpreheated by steam in order to ow freely in cold weather or to vent the clog g of the a aratus.

A further ofict of the i vention is to'providea lubricator in which the oil is forced steadily and regularly into-the steam-chest. .by live-steam pressure, in which the sightfeed is constantly under the eyeof the en inee'r, and which is easily regulated by t e] The invention consists in theconstruction and combination of parts to be moreful y described hereinafter an particularly .set

forth in the claims. e Reference is to'be had to the accom anyin'g drawing, in which the figure is a si e elevation of our invention, showing the same applied to a steam-engine cylinder and showi a part in vertical cross-section.

efore proceeding to a more detailed exlanation of our invention it should be unerstood that we employ an oil-chamber ha ving a steam-jacket around the same, into which live steam is introduced to prevent, the oil from freezing or becoming clogged.

The invention is particularly useful in connection with steam-engines intended for use in the open, such as traction-engines or the like, in which when used in cold weather the oil is liable to be affected by the low temperature The oil is injected into the cylinderby means of live-steam pressure and through a sight-feed having an injecting-nozzle, b means of which theoil is forced from the oi the usua t chamber drop by drop, and the flow through is regulated by means of a needle-valve of the usua construction. L

Referring more particularly -to-,the draw;

ing, 1 re resents a steam-engine cylinder of e, having a steamechest 2, within which is ocated a slide-valve. A steampipe 3 having'a throttle-valve 4, leads to the steam-chest and provides means for the entrance of the steam thereinto. An exhaustpipe 5 leads from the steam-chest to the atmosphere or to a condenser in the usual manner. I

We provide a cylinder 6, formed of .castiron 'or other suitable material; "having threaded ends upon which are screwed cylinder-heads 7 and 8'. The cylinder-heads 7 and 8 are screwed tightly into place and do not require the use of gaskets. Within the .cylinder 6 is located. a smaller cylinder 9, having similar cylinder-heads 10 and 11,

screwed upon ltsthreaded ends, 'as'in the cylinder 6. A pipe 12,having threaded ends,

is screwed into properly-threaded openings in the cylinder-walls and affords communication to the inner cylinder through the steam-jacket chamber 13, formed between the cylinders. A -screw plug or cap 14 is used to close theopening of the tube 12, which is intended for the purpose of filling oil into the cylinder 9, which constitutes the oilchamber. A similar pipe 15, having threaded ends and fitted in proper tapped holes through the lower sides of the cylinders, con-' stitutes a drain by means of which the cylinder 9 maybe emptied, if so desired, and is provided with a, etcock 16 for the purpose. A

petcock 17 is ocated in a tapped opening inv the lower side of the cylin er 6 to afford means for draining the same.

A steam-pi e 18 leads from the steam-pipe '3 to the e inder-head 8, at whichut is screwed to t 1e end of a short pipe 19, having threaded ends screwed into'openings in the cylinder-heads 8 and 11, thereby effecting communication between the steam-pipe 18 and the oilchamber. A branch pipe 20 leads from the pipe 18 and opens through the cylinder 6 into the steamjacket between the cylinders. The branch pipe 20 is provided with a throttle-valve 21, by means of'which communication betweenthe pipe 18 and thev Patented Nov, 27,1906,

steam-jacket 13 may be shut off. The 18 has a similar throttle-valve 22 between the branch i e 21 and the steam-pipe'3 and a secon t hrottle-valve 23 between the branch pipe 21 and the cylinder-head. V mThe pipe 24, having its threaded ends screwed in roper openings in the cylinderheads 7 and 10, effects communication between the oil-chamber and a sight-feed 25 through a pipe 26. The sight-feed may be of the usual type and has an inj ecting-nozzle 27, the flow through which is regulated by a needle-valve 28. The sight-feed, further, has a glass-tube section 29, through which the flow of the oil may be watched by the e 'neer.

A pipe 30 leads from the sighteed to a second pipe 31, which communicates with the steam-chest 2 of the engine. A pipe 32 eifects communication between the pi e 30 and thesteam-jacket 13 and is provide with a throttle-valve 33, by means of which this communication may be shut off. Above the pipe 32 the pipe 30 has a similarthrottle-valve 34, by means of which the flow through the pipe may be adjusted. A by-pass pipe 35, raving a throttle-valve 36, opens communication from the pipe 32 to the exhaust-pipe 5 of the en 'ne. j

The oi -chamber, constituted by the cylinder 9, may be filled through the pi e 12. If

the temperature is such that the oi needs no heating, the valves 21, 33, and 36 are closed, while the remaining valves are opened, permitting the flow of steam through the pipe 18 into the oil-chamber. The steam-pressure forces the oil out into the sight-feed.

It will be understood that from the condensation of the steam there will be a certain amount of water or steam and water in the pipes 30 and 31, and consequently as the oil, with a small uantity of steam, is forced out through the sight-feed the drops of oil will bubble up through the moisture and so be injected with the steam into the steam-chest for lubricating the valves, piston, &c, However, if it is desired to heat the oil the valves '21 and 33 are opened, whereby the steam is permitted to flow through the steam-jacket 13 and to circulate about the inner or oil chamber, thereby thoroughly heating the same. The steam then flows out from the steam-jacket through the pipe 32 and may enter the steam-chest through the pipe 31, together with the oil. If so desired, however, the valve 33 may be closed and the steam may pass through the by-pass pipe 35,

the valve 36 being 0 en, and so flow into the exhaust pipe 5. he flow of oil may be regulated at the sight-feed in the usual man ner.

Having thus described our invent-iomi'wc claim as new and desire to secure by Letters Patent- 1. A lubricator comprising an oil-chamber having a steam-jacket, means for admitting oil-chem jacket therebetween, a steam-pipe communieating with said inner cylinder through said pipe I steam to said chamber and to said jacket, a
